Images of guard cells and overview of guard cell ABA-regulated genes and leaf ABA-regulated genes. (A) Bright-field image: Epidermal peel with intact guard cells after partial cell wall digestion. (B) Fluorescent image: Vital staining of epidermal peels with FDA reveals that guard cells are the only intact cell type. (C) Overlap of guard cell ABA-induced genes and leaf ABA-induced genes. (D) Overlap of guard cell ABA-repressed genes and leaf ABA-repressed genes.
